In 1992 JAMA published an article by the Evidence-Based Medicine Working Group focusing on the role of evidence-based medicine (EBM) in medical education.1 Although the term evidence-based medicine first appeared in the published literature the prior year,2 the JAMA publication brought both the label and the underlying philosophy to the attention of a wider medical community.
The article was audacious in suggesting that EBM represented a new paradigm in the teaching and practice of medicine by deemphasizing unsystematic clinical observations, pathophysiological inference, and authority. The article honored traditional skills (eg, understanding biology, demonstrating empathy), but emphasized new skills that learners must acquire and use: question formulation, search and retrieval of the best available evidence, and critical appraisal of the study methods to ascertain the validity of results. The article aggressively presented EBM as a fundamentally new approach.
